Unless extreme care and a good torque wrench is used for tightening fasteners, there is a good chance that they could be over-torqued and crack the frame. As for wear and tear, I have seen CF frames that have been ridden hard that are still holding up 10 years after manufacture.
Wheels are a little different, but only slightly. A big guy like you will want to have wheels that have a little higher spoke count. A wheelset that has cross 3 spokes with a count like 32 rear, 28 front would be good for you. Just don't try a wheel with 20 or less, or a radial spoke pattern as they would probably not be strong enough for your current weight and would be going out of true often, if not breaking spokes altogether.
So, to sum it up, you can ride a CF frame but make sure that you are getting strong wheels.

I have looked at several bikes so far. I want something in the "endurance" or (as I have seen the word ) "plush" catagory, perhaps more comfortable than a racing bike, with a longer wheel base.
I have read several reviews of the Jamis Ventura 2. At $2100.00 this is about the top of what I would want to pay. I have also looked at the 2010 Scattante Elite by Performance. Both of these are CF. They are light, with good components. The sales people say CF is a smoother ride than metal. On the other hand I have seen lots written on different forums about why someone my size should not ride CF. The most dramatic image: one pot hole and the thing will explode sending shards of graphite through various parts of my body. Other comments include that a cf bike won't last a long time ie several years because it doesn't tolerate long term wear and tear.
Another issue I have read about is the need to have very good wheels to avoid flexing for someone my size
So is there some straight advice out there. Happy to have someone direct me to a sight or prior thread to sort through this. Question is: CF or not for a big guy like me.
You can ride a CF bike with no problem. The bigger question is why would you? In my opinion I think you would be better off buying a high end Aluminum bike instead of a entry level carbon bike. You can purchase a Specialized Secteur or a Cannondale Synapse these road bikes have a more upright ride feeling so it feels more comfortable on long rides. You can use the money you save to buy gear and better wheels if you choose. Don't buy a bike without test riding everything in your price range. Don't Buy a Bike online.
